C0110 04 or C0110 06

A short to ground or an open/high resistance is detected on the pump motor B+ circuit.
The electronic brake control module detects a low voltage in the pump motor supply circuit when the feedback voltage is less than 4.5 V for greater than 150 ms, and the pump motor is not activated.

The pump motor continues to rotate briefly after deactivation creating a feedback voltage. The electronic brake control module sets the DTC if the measured feedback voltage indicates a binding or stalled pump motor.
